Getting excited about what we don't know!

Hi everyone!  It seems like a lot of the eco websites and blogs I read are a lot of doom and gloom.  There is no doubt in my mind that we are doing bad things to this planet, but we have to remain hopeful for improving our ways, as well as remain hopeful for that which we do not know.  I was recently reading the December issue of National Geographic and they had a snippet about some of the fieldwork that is being done by scientists, archeologists, and the like.   I read about a group of scientists on the island Vanuatu (which is in the South Pacific).  Over 5-months 150 scientists went over the island studying species.  Over 10,000 species were found, 2,000 of them may be completely new to science.  It is quoted by French mollusk expert Phillippe Couchet that "80 percent of the world's species remain to be discovered."  What an amazing thing to think about since most of the animals, plant life, etc. we hear about are going extinct!  Hopefully we can continue to discover WITHOUT harming natural habitats.    Reading that article made me hopeful for what our future here on earth holds.
